Breaking: Michael Burry said "it feels like the last months of the 1999-2000 bubble"

History is rhyming hard right now:

1999:
• Knicks are in the NBA Finals
• Nasdaq up 84% that year
• Tech was 33% of the S&P 500
• CAPE ratio hit 40x
• Margin debt at record highs
• Hedge funds had 31% of portfolios in tech

Breaking: OpenAI fired Leopold Aschenbrenner at 22. Three years later, he manages $5.5 billion

His next 13F files this Friday and the new trades will be posted here

Leopold is quickly becoming one of the best AI investors out there

And it started when he got fired from OpenAI in April 2024 for a leaked memo on AI safety

Instead of moving on, he spent 6 months writing a 165-page document predicting AGI arrives by 2027

Then he launched Situational Awareness LP. Backed by the founders of Stripe and the former CEO of GitHub

Here's what he bought:

• Bloom Energy (BE): powers AI data centers. Up ~1,420%

• Lumentum (LITE): optical components connecting AI chips at scale. Up ~1,335%

• SanDisk (SNDK): storage layer for AI workloads. Up ~3,130%

• CoreWeave (CRWV): GPU cloud for AI training and inference. Up ~166%

• Iris Energy (IREN): AI-focused compute infrastructure. Up ~585%

Every AI model that gets built needs power, somewhere to store data, and compute to run on. He bought all three before anyone else was paying attention

Update: It's been 137 days since Warren Buffet revealed Berkshire's purchase into Google $GOOGL

It's up 4% since 

Never in history has the S&P 500 been carried by fewer stocks

Right now, only 42 of 500 are responsible for pushing the market higher

Historically, that number sits around 100

And those 42 are being led by just 5:
• Alphabet $GOOGL
• Nvidia $NVDA
• Amazon $AMZN
• Broadcom $AVGO
• Apple $AAPL

Every other time the market got this top-heavy, a pullback followed

The last time it looked like this: the Dot-Com Bubble in 2000

Breaking: Michael Burry bought the dip on LuluLemon

According to his substack

"I substantially increased my position in LULU in the low-mid $110s on the post-earnings dip.

While everyone sold, Michael Burry bought $UNH .. now up ≈ 36% since his 13F dropped in August.

It was his largest bet, nearly 19% of Scion’s portfolio

• Robinhood: $612.5M → $4.9B (+700%)
